"Unknown SIM Error" on MDA Pro on T-Mobile

Hi,
I just bought an MDA Pro direct from T-Mobile's website and it was delivered today. Unfortunately, while the PDA side of things works perfectly, it won't connect to T-Mobile at all.
On the 'T-Mobile' start up screen it displays the text 'No GSM' above what I think must be version information.
It reports 'no service' in the phone status bubble, and SIM Manager says: "Only emergency service calls can be made without a PIN" When I enter the PIN I was given, nothing happens. I think it goes into 'change PIN mode' because then I can put two more 4-digit numbers in (it doesn't matter which!) and then it says "Unknown PIN Status. Unknown PIN Error"
Unfortunately it isn't just a SIM problem as the SIM works in my O2 P800.
I've spoken with T-Mobile and they want to swap the handset, which would be fine if they had any in stock! I'm wondering if anyone here had any advice on ways I could try fixing this short of waiting for them to get in touch and tell me they have another handset I can try.
Any suggestions would be much appreciated!

Hi,
what is your local provider ? Is it T-Mobile, Vodafone, E-plus or O2 ?
The mda pro only works with a t-mobile sim !

Try to clean the sim before putting it back in the MDA Pro,
Generally works for me!

i had the same problem with my jasjar here is Australia......my sim works on any other pda and phones but not the jasjar.....apparently the sim that i have or some of the new sims have a little higher voltage than normal.......and the jasjar dont like it.....so what i did was replace the sim with another one and that worked......al they had to do was port my number to the new sim......but before it did that tried to put the sim in first and it started to look for a network so i knew this was gonna work......becoz before when i put my old sim in it just says invalid sim or no sim........so try replacing ur sim with another one......perhaps try and get an old sim maybe the sim has some in stock.....i bet ya that will wrok....good luck

Thanks guys ... I'm trying to find an older T-Mobile SIM to try. It's just frustrating! I've tried giving the SIM a wipe, to no avail. If it is that the SIM is slightly incompatible, T-Mobile sending out another unit won't really help, right?
How annoying!
If anyone else has any great ideas I'd love to hear them!

try using someone elses sim and put it in the device and give it a try to check if its definitely the unit and not the sim......when i rang the tech support for optus thats what i was advised.....and they were right....sim voltage was the problem......anyways try getting another sim.

Contact customer services.
The problem sounds like you SIM is too old.
They should ask for your SIM serial number, if its too old they'll offer to send you a new SIM or something else to make it work straight away??? :wink:

The MDA PRO as its a 3G type phone with WCDMA it needs a diffrent sim card that is usaly known as a 3V USIM.
Its the same on Three in the UK, the sims from their phones will only work in 3G phones not standard GSM ones and vica-versa.

Old SIMs (from about 5 years ago) are rated at 5 volts. Newer ones are 3 volts (not just for 3G). Trust me, I work for a certain mobile phone company who sponser West Brom. ;-)
The problem will be fixed in a future software upgrade. But for now you need a new SIM or your phone unlocked.

Trouble is, this *is* a new SIM... I'm moving back to the 'hardware fault' diagnosis I think.
I went to a friendly carphone warehouse shop in Oxford and tried a new (and definately working) T-Mobile PAYG SIM and that gave exactly the same error.
Maybe T-Mobile need to send me a 3G SIM. I guess I'm probably just going to have to wait until they can send me a new handset to see what happens.
Ho hum!

There's no such thing as a 3G SIM. The 3G gigery pokery happens on the phone. There is no need for a different SIM. The MDA Pro has a problem with SIMs with certain serial numbers (Don't know which coz I'm not at work). You need either a SIM that the phone likes or your phone unlocked. Call customer services if you still have your phone.

Had the same problem allready twice in 2 weeks.
One time a soft reset made the device working again - another time I had to take out the sim card and put it in again, then it worked. But all email accounts were gone and had to be installed again.

Hi, thanks for that reply... it seems very useful! If you could post/pm me the numbers of those SIMs that the MDA Pro is unlikely to like I'd really appreciate it... customer services aren't striking me as very helpful (and certainly not knowledgable) and I can tell that if I call them they're still going to say: Wait until we have another handset in stock and we'll see what happens then. Which doesn't help me much as who knows when that will be?
Thanks!

Any SIM serial not starting with 06 or 07 will be affected by the issue.
eg 90043575, the serial starts with 04.
This will be fixed with a software upgrade in the future, in the mean time you either need new SIM or you handset unlocked. For either call customer services.

I got my MDA Pro a few days ago also, had the same problem as you, basically the handset is network locked, not sure how they managed to lock all UK network, basically give Tmob a call and make sure your stay on the line until they provide with an unlock code, i got mine, now my old sim works and my handset is unlocked

i had the same problem with my ASUS P535 (here is France) with new SIM card.
seen from :http://vip.asus.com/forum/view.aspx?id=20070818011855796&board_id=6&model=P535&page=1&SLanguage=en-us
Thanks.

I had the same problem BUT-
I had the same problem but i had been using the sim card successfully with the exec for a year, after a hard reset it doesnt recognise the sim. will a ROM upgrade fix it or is it a hardware failiure?

I had this happening to me just last week with a card that works all the time. Then followed that I had no sound coming off speakers or bluetooth. In my case it was a third party software problem. Don't ask me which as I install and uninstall too many applications and my Uni gets in a tangle sometimes. A soft reset instantly (in terms!) restored phone activities and sound, so I recommend a reset if you haven't tried it already. Maybe you will need more than one.

Sim Unlock My Wing

I just inherited my brother's phone, a wing he used in the states and i owuld like to use it in the UK. can anyone please help? im dying to try this manificent phone

google IMEI CHECK

i know about imei check but i was hoping there would be a free solution out there

unfortunately not at this time for the Wing.

Is the Sim Unlock Available for Wing
Is the Sim Unlock available for Wing Now or still not. Any help will be really appreciated.

No. it's been 2 days! haha

THIS IS THE ONLY WAY TO SIM UNLOCK THE PHONE FOR FREE.
Have a T-Mobile user put their SIM card into the phone and call 611 from the phone. Go to Customer Service and inform them that you will be leaving the country and would like to unlock the phone so you can use international prepaid SIM cards to call your aunts and uncles in *insert non-US country here*. They will give you the unlock code for the phone.
This will only work if the T-Mobile user has had the T-Mobile service for more than 30 days. If you are able, have your brother do it from his SIM card since he had the phone previously.

Thanks for the advice. Works!

Ok, just for conversation. Lets say I want to get a new wing with my equipment protection from Tmo. Does a SIM unlock on my old wing make it useable for others?

Equipment protection? Huh? Are you talking about getting it replaced with the insurance? and giving your old one to someone else?
When the phone is locked, it ONLY works under T-mobile.
When the phone is unlocked, it will work with any carrier, ie TMO, ATT, etc..

How about Vodafone NL..
Is there any free solution to sim unlock it ..?

Anyone with a Herald/Atlas or any of its variants ... are all in the same boat. There's no free unlock solution as of yet.

AT&T and T-mobile both have the same policy on unlocks:
- Account must have existed for at least 3 months
- Must not have had an unlock request within the last 3 months
- (Generally) Must be outside the Buyer's Remorse period (30 days)
- Must not be one of the 'special' phones (Sidekick, iPhone)
If the Wing is an upgrade to your existing service, you can get it unlocked after 30 days.
New customers must wait 90 days.
Simple workaround: If you know someone on T-Mobile with an available unlock (one per 90 days, remember), you can just give them the IMEI number, make & model, and they can unlock it from there. They do not check if you're calling from that phone -- but the phone must still belong to the carrier/be branded with that carrier

SO if my phone is "lost" and i get a new phone. Is myold wing good to go for someone else?

Faulty diamond 2?

Hi
I have just bought a diamond 2.
I have put my SIM card in and when I switch the phone on it comes up saying the SIM is missing. I have tried cleaning the SIM and re-inserting and even padding out with some paper. Unfortunately none of this has worked and the phone remains just as useless to me.
Apparently it is SIM-locked to O2, I am using a working O2 SIM. Does this mean that it might be SIM-locked to someother network or is it a hardware fault or could it be something else?
I have tried plenty of searching but that has yielded nothing so far.
Thanks for any answers
Jim

Hi
Have you bought this second hand? Perhaps it is locked for contract use and you are using Pay As You Go? It might also have been reported stolen and deactivated.
Do you know the SIM works, have you tried it in another phone?
Options are, try another O2 SIM, if that doesn't work contact O2 and ask them to check it, they might be able to tell you why the phone isn't accepted on their network. Alternatively contact the seller maybe?
If it is new of course take it back to the O2 shop and get them to check it, it could well be faulty.
Regards
Phil

Thanks for your response Phil
I have tried 2 different working O2 SIM's in the phone and they both don't work.
I'm thinking that because its saying SIM is missing it is not seeing the SIM as opposed to it being SIM-locked.
I have contacted the seller and he insists that it worked fine on O2.
I am really dissapointed as I was really looking forward to using this phone

I had exactly the same when I first powered up my TD2 - and I know my SIM worked.....
I found that I cleaned the sim by running on my t-shirt (obvious) - and then reinserted - with the same problem....
Then I pushed the card hard in both lateral and vertical directions - push the end of the sim towards the edge of the phone and then push down on the sim - it didnt even look like it moved to me - but when I put the battery back in - presto it worked.....

I'll give that a try, thanks

no joy with that.
Thankfully the seller has offered me a refund, just need to buy another one sharpish

SIM network unlock PIN for Samsung Galaxy S

Probably a silly question but I have the following problem:
I have 3 cards (Orange and 2 x T-Mobile). When I put either T-Mobile SIM in my phone, it requests a SIM network unlock PIN. I have the option of entering this in or clicking a dismiss button which will take me pass this screen but doesn't register onto the GSM network. This doesn't happen on my Orange SIM as this registers straight away onto the GSM network.
All 3 SIM cards do not request a PIN when I use them with two other phones that I have (HTC Hero and HTC TyTn 2).
On the SGS I have tried the pins 0000, 12345 and 1234 which are default PINs that I recall. I've checked the manual for the SGS and the literature that came with my T-Mobile SIM card and neither give any hints about a default PIN or about a SIM network unlock PIN.
I'm not sure if the PIN request is coming from the phone or the SIM card. I'm guessing it's coming from the phone but I don't know why it doesn't request this when I use my Orange SIM card.
I purchased the phone SIM free. The Orange SIM is a PAYG and the two T-Mobile SIMs are pay monthly contracts. I know all 3 SIMs work without PINs in my other phone.
Can anyone help? I'm assuming I'm missing something really simple but can't figure out what. I've already tried a dozen google searches with no luck. Please please help. I feel I'm being deprived of my 2 hour old SGS phone

I've now taken a video of the boot up sequence to show you what it looks like: http://www.youtube.com/watch?v=3D-RvvCK2bM
Can anyone confirm or refute whether this is happening on their SGS too? It seems like it's a Security Code on the handset but I can't find any setting for such a code.
Any help will be greatly appreciated.

Don't think your phone is actually SIM free... no issues here using any SIM I like (purchased from Unlocked Mobiles). Where did you get yours?

I purchases it from handtec. I don't think it is Sim free for the following reasons:
1. It was listed as Sim free
2. The box it came in also seems to indicate it is Sim free
3. There is no carrier logo on the phone or anything it came with
4. Seems to work with my Orange Sim card (which implies the phone came from orange if it was Sim free and this phone hasn't been released on Orange).
I'm guessing by the single thread reply that no one else has come into this issue before? And it's probably not just a simple default security code?

I don't know if this will help, but when I was asked for a sim code on a new Nokia phone, about two years ago, I rang Voda and asked for the pin code. In your case you would need to ask T Mobile.

I have the exact same issue with my Galaxy from Handtec which arrived today. I hope they aren't selling sim-locked phones as sim-free... Time to call Voda...

Ok, apparently it's a known issue. Just spoke to handtec, they say they got a batch of phones from Samsung which are locked to Orange. Call them for a replacement/refund. Don't mess about with the phone support line, it just points you to the website and disconnects you, call them and speak to sales. 01733 298500

Ah ok, that makes sense and which is why my Orange SIM card worked but not T-Mobile. I may have come to this conclusion if I had a Vodafone and O2 SIM knocking about.
Thanks for the info. Will be returning the phone for a replacement.

@n4nick: It appears as though you were right although the phone doesn't look like an Orange locked phone. Orange are notorious for plastering their big ugly logo on the physical phone and all over the software. They even put their logo on the box, accessories and manuals. This phone really looks like a SIM free version.
I wonder if the Orange locked batch were due to go to Orange for them to do their usual carrier differentiation before they then go out to customers.

Hi!, I've bought Samsung Galaxy S from handtec too and I get the same message: sim network unlock pin. I've just sent request to Handtec support.
What about you? Did you somehow unlock? Or did you change your phone?

Speak to Handtec about it and get a replacement or a refund as the item sent out is the wrong item. As mentioned previously, I believe the mistake was from Samsung as they sent a batch of Orange locked handsets as unlocked handsets which Handtec then sold accordingly. Handtec seem to be handling the whole mixup very well with good customer service so you should be ok.

Yeah I'm experiencing this issue as well. Phone worked fine for 7 days then today out of nowhere I get the SIM network unlock PIN alert upon startup. I contacted Handtec and this is all they had to say.
Thanks for your email,
Unfortunately this is an error with Samsung and we will require all of the items back, postage will be covered once back and confirmed it is an orange locked device but we will require this back to replace it for you.
Please advise,
Kind regards.

I can't be bothered with sending it back and being without a phone for atleast a week.

Legally they have to give you a full refund including the postage cost for both ways. Therefore you could purchase a new handset while you are in the process of getting a refund for the existing one. You'll know if it is an Orange locked phone because there was one or two Orange specific applications pre-installed on the phone.
If it was working before and not now then it's possible it could be a different issue though.

I work for t-mobile and samsung sent us some unbranded phones that were locked to orange by mistake. That chances are we wernt the only ones to receive them
Sent from my GT-I9000 using XDA App

had this problem myself on O2
went to store to use their phone to ring around (they were sorry)
after time on the line with O2 support they had no answers, so i rang samsung
samsung took literally seconds on the phone, i said about the 'sim network unlock pin' and he simply turned round and said its dead, a dead chipset thats in every phone they sent out in the last week, i was told this on friday 11th
samsung then spoke to the staff at the O2 store and advised them to mark all other galaxys they had as 'dead on arrival' and return them and for others to do the same
looks like a big batch issue so best thing u can do is send your dodgy one back like i have done, hopefully this replacement will work

I just got the Network Unlock PIN Message myself randomly after a reboot 7 days after purchase.
Has anyone tried using a TurboSIM to see if it works?
Sad thing is it was working one day and then broke the next.
Pretty bad that we have to pay postage to get their doa replaced. ( Specially considering that's about $50 for me. )
EDIT: Does anyone know what the STOCK firmware was when you got your handtec handset? ( From what I can tell it could be XXJF3. )
EDIT2: Success! After contacting Handtec they sent me a code to use, it seems to have permanently network unlocked my phone.

After a few emails with Handtec they were able to provide me with an unlock code after giving them my IMEI number. All is good again

I have a similar problem with T959 from TMobile USA. The phone was obviously locked to TMobile but I got the code from TMobile, entered it and phone was unlocked. My customer took home, used it for about a week and now the phone is network lock again and ask for network pin. So I enter the same code that was used to unlock it but now it DOES NOT work. So strange. But this happened before on other android phone and it worked, just re-enter the code. Anyone has a solution yet on this problem?

aaarrrggghhhh!
I have same problem but.... the unlock code Handtec sent me does not work
I have tried every method I can find on the internet to enter the unlock code (eg #0111*code#, #7465625*638*code# and even #7465625*638*# which pops up with a seperate box to enter the unlock code) and each time it fails. I've even done this after various full hardware resets.
Hantec have said the phone might be faulty with a software problem and to send it back to them.
I am in Cyprus and its going to cost me 50 euro to send it back. If I had paid an extra 50 euro on the Handtec price I could have bought it locally! Doh!

To enter the code you should put a SIM in, and start the phone, it will ask you straight away...
If you attempted to enter wrong codes too many times it will stop asking you and your phone is permanently locked until you return it to the manufacturer.
Oh noes, mine better not relock... :\
Just out of curiosity, how many 5's does your code have?

[Q] Unregistered Sim Problem - afraid that it might be stolen (Rogers)

Hello there,
So I got a USED Galaxy S4 from someone on kijiji
The phone is from rogers, and still locked to rogers/chatr
Iv been using the phone for about two weeks with no issues at all.
Last week, just in the middle of the day
I was taking the phone out of my pocket, and I noticed that it says ' unregistered sim'
On the lock screen and status bar
Tried to restart the phone and pull out the battery, nothing happened. Tried a NEW chatr sim card- no luck.
Went to rogers yesterday, tried 4 different sim cards
Didnt work.
I stuck with the "unregistered sim" msg, which not allows me to use the phone.
I tried to look for an answer around the net, and couldnt really find someone who have a similar issue.
Any ideas?
Is the phone might be stolen?
Is therr anything to do about it?
Thank you!

Sounds like you're the victim of insurance fraud. The guy sold the phone and then reported it stolen. He gets paid twice. You should have insisted that the phone got transferred to you at an at&t site, or whoever the carrier is

If the phone is blacklisted, another possibility is that the phone was stolen directly from Rogers or an authorized dealer. Phone will work for a while until the IMEI is blacklisted for that carrier.
Try to unlock the phone and use a different carrier sim card like Telus or Bell.

You could have a defective SIM card slot. As to my knowledge no carrier in Canada currently blacklists IMEI's (I could be wrong though). An easy way to check is just to call Rogers and provide them the IMEI and they can tell you.

I work for a multi-carrier dealer and I know that for Telus if you get their replacement plan (the one where they charge you monthly for) and you report the phone lost/stolen they will blacklist the phone. Rogers has the same replacement plan but whether they blacklist the phone or not I don't know. Try putting a sim card from a different carrier and see if it works. If it does then the phone was most likely blacklisted by Rogers/Chatr/Fido.

They would tell you that the phone is blacklisted. I am going with a faulty sim cradle on this one.

Thank you guys
Thanks a lot guys, very appreciate your fast and helpful comments!
Ill definitely try to unlock the phone and try use it with another carrier!

reason for unregistered sim error
You have samsung galaxy mobile and you have bought it from someone else.
Here is most possible reason is the original owner might have not paid any due amount or some one complaint about the phone from insurance company that it is lost or stolen.
It is locked phone still you can try another sim from same carrier like roger.
Or if you mobile support dual sim then try to insert the sim to another sim slot.
Or you can also try to insert sim to another mobile which is not locked. On unlocked phone if you get the same sim unregistered error. Then contact your sim provider and they will ask for your id proof. And photo. Just submit it and your sim will be active.
